King Felipe and Queen Letizia said they are "moved and concerned" after a serious train accident on Wednesday morning.
The Spanish royal couple sent their condolences to the friends and families of those affected after two high-speed trains crashed in the Toledo province, killing at least 64 people.
The King, who was visiting a military base on Wednesday morning, appeared deeply emotional and on the verge of tears as he spoke to media in a video shared by the Royal Palace.
Posting a statement to their social media accounts, the King and Queen, who are parents to Princess Leonor and Infanta Sofia, said: "We are moved and concerned by the train accident in Urda (Toledo). We share in the sorrow of the families and loved ones of the deceased and send our affection to the injured and those affected.

Felipe was visiting the Jaime I military base in Bétera (Valencia).
After the exercise concluded, he explained to the media that it had been shorter than usual so he could return to Madrid as soon as possible and monitor the emergency.

Prime Minister Andy Burnham said his thoughts are with those affected by the crash and has spoken to the Prime Minister to send his condolences, while the UK's ambassador to Spain, Alex Ellis, has said he is following the "terrible incident" with "deep concern".
It is Spain's second deadly rail accident this year, following a crash in January in the Cordoba province when a train derailed.
King Felipe cancels official engagements
Following the accident, the Spanish monarch has cancelled all his engagements for Wednesday and Thursday.
It means he will no longer be attending a commemorative concert at the National Music Auditorium, not the closing ceremony of the World Infrastructure Forum.

"I always send words of encouragement and support to all the emergency services who are attending to the situation. I understand there are people from all agencies and backgrounds, including the Armed Forces and the Military Emergency Unit (UME), because many people are responding to the emergency."
